I noticed a few weekds ago that my autocad was beginning to slow down opening and closing drawings. I primarily noticed in the projects that were paper space models space with multiple drawing tabs (3-4) and xrefs but now it is every drawing that I open whether it's done in paper space/model space or just in model space... I thought it was that there are too many layers but that doesn't seem to be the problem, especially since this just started happening. Anyone have any suggestions?
Does this happen on a computer? Does your computer have a processor, RAM, graphics card and Operating system? Are you working over a network?
Make sure your Properties Palette is completly closed, not minimized or docked etc. Are you running any LISP, add-ons or third party apps?
Does it open the files at some point or just hangs?
Have you installed any antivirus?
As a test, try disabling your antivirus or even uninstalling it to see if it makes any difference.
